You cannot. You need to know the height as well.
If you know the height, the surface area, A is given by
A = 2*Ï€*r2 + 2*Ï€*r*h where r is the radius and h the height.
use algebra to find the radius, then plug the height and radius into the surface area equation
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Entire surface area of a cylinder = (2*pi*radius2)+(diameter*pi*height)
pi x radius^2
Split the cylinder into two circles and a rectangle to find your answer.

2(pi)(r)(h)=the area of the curved surface
First, you figure out what the area of the top of the cylinder is, which in case is pi times radius squared. Then, you multiply the answer by two. Next, you find the lateral surface area of the cylinder by multiplying the circumference times the height. Since the problem only gives us the radius of the cylinder, we use the formula, two times pi times radius times the height, in order to find the lateral surface area of the cylinder. Now the final step. Add the answer you got for the first step, plus the lateral surface area of the cylinder, and this should give you the surface area of the can of soup.
h = ( Area/ (2pi*r) ) - r h = height r = radius pi = 3.14
To calculate the surface area of a cylinder, you can use the formula ( SA = 2\pi r(h + r) ), where ( r ) is the radius and ( h ) is the height of the cylinder. If you provide the values for the radius and height, I can calculate the surface area for you. Otherwise, you can substitute the values into the formula to find the answer to the nearest hundredth.

half the diameter and then get the radius times pi and square it
